I'm using VS2008. I can receive data fine with HyperTerminal and python but I keep getting parity errors every time I try to transmit a character to C#. Number's work fine, it's just the characters. It's configured exactly the same as HyperTerminal: 9600baud, 1 stopbits, no parity, no handshakes. What could be causing only the characters to mess up and not the numbers? c# serial-port parity share|improve http://stackoverflow.com/questions/2210316/c-sharp-serial-rs232-parity-error this question edited Oct 10 '12 at 19:52 dsolimano 6,10832746 asked Feb 5 '10 at 20:49 ilia choly 8,194647100 1 How is your text being encoded? Can you post a small sample? –Dave Markle Feb 5 '10 at 20:52 It's not encoded as far as I know. I'm just sending one char at a time out the UART port on the PIC (dsPIC30F1614A if it matters). Or maybe I'm misunderstood your question. –ilia choly Feb 5 '10 at 21:07 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted How can you have parity errors when the configuration is "no parity"? Are you seeing failures of a checksum stored in the data stream (as opposed to RS-232 parity bits)? Are you getting exceptions when using the C# serial port class? Show some data dumps. You might also try realterm, which can show you the hexadecimal value of raw characters received. It's also easy to convert C# byte arrays into hex. Then compare both to see if characters are missing or changed or what the actual problem is. We can't suggest any solutions until the failure is described a little better. share|improve this answer answered Feb 5 '10 at 20:55 Ben Voigt 202k20238454 There are no exceptions. It's just printing out

In the following program the console prints lots of c# serial port !!!!! but no ?????, why? Also I'm assuming that the byte with the invalid parity bit will still be included in the stream? using (var serialPort = new SerialPort()) { serialPort.PortName = "COM2"; serialPort.BaudRate = 562500; serialPort.Parity = Parity.Space; serialPort.DataBits = 8; serialPort.StopBits = StopBits.One; serialPort.ErrorReceived += (s, e) => Console.WriteLine("!!!!!"); serialPort.Open(); var thread = new Thread(() => { while (isRunning) { var b = serialPort.ReadByte(); if (b == 126) Console.WriteLine("?????"); } }); thread.Start(); Console.WriteLine(""); Console.WriteLine("Press any key to exit."); Console.ReadKey(true); isRunning = false; thread.Join(); } c# serial-port parity share|improve this question asked Mar 27 '13 at 19:43 ronag 18.9k1375152 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted It is a documentation bug.
